RESILIENT LAMP-SUPPORT.

Specification of Letters Patent.

l aten'ted allay Jill,

Application filed January 3, 1910. Serial No. 538,009.

To all whomdt may concern:

Be it known that I, ALFRED VVooDLnr,

,7 resident of 132 St. James street, in the city ments in Resilient Lamp-Supports; and l do'hereby declare that the following is a full. clear, and exact description of the same.

The invention relates to improvements in resilient lamp supports, as described in the present specification and illustrated in the accompanying drawings that form part ofthe same.

The invention consists essentially in the novel construction and arrangement of parts whereby a lamp bracket is connected to a lamp by a resilient member detachable from said lamp and bracket.

The objects of the invention are to prolong the life of lamps, particularly electric lamps especially where the fixtures are sub ject to vibration, to hold the lamps firmly to the fixtures in the desired position and gen orally to construct a neat, simple and inexpensive device for the said purpose.

In the drawings, Figure 1 is a view showing an electric lamp, a. portion of a fixture and the invention connecting said lamp and fixture. Fig. 2 is a vertical -sectional view of the resilient support. Fig. 3 is a perspective detail of one of the thimbles.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 and 2 are the thimblcs here shown having the central threaded orifices 3 and 4 respectivelyand the recesses .3 and (3 on the inner sides. In each of the thimbles, the wall of the recess converges slightly from the knurled edge 7, so as to form said recess larger at the bed than the opening thcreinto.

8 is a helical spring flaring outwardly at each end thereof and inclosed in the recesses 5 and 6 and as said recesses have walls converging to the opening, the said springs are very rigidly held therein.

The forn'iing of the recesses in the manner particularly described herein is only one way of securely holding the resilientmember to thc thimhles and the said resilient member may be secured to said thimbles in other ways;

9 is a union screwed into the threaded orilice 3 and joiningthe resilient support to the lamp 10.

11 is a portion of the fixture screw held -in the threaded orifice 3 in the thimble 1, thus securely joining the fixture 11 to the lamp 10.-

It will thus be seen that the lamp is held securely from the fixture by resilient com nection which will prevent any jar to said lamp through any vibration of the said fixture, in other words, the lamp will gently sume its place after any shaking and in fact at every motion of the said fixture, the spring will avoid any rigidity always due where there is a rigid connection between the lamp and the fixture.

The exact construction of the thimbles and spring has been described herein, but -it must be understood that without departing from the spirit of the invention, modifications may occur in the arrangement and the making of the parts. 1

This invention is particularly applicable to electric lamps, though it may be applied to gas and other lamps with suitable changes.

What I claim as my invention is:

1. Ina resilient lamp support,'a helical spring having flaring ends and thimbles having converging walls and closelygripping the flaring ends of said helical spring,

said thimbles having central threaded orifices therethrough adapted to screw on to the light fixture and lamp respectively.

2. In a resilient lamp support, the combination with a light fixture and a lamp sup ALFRED wooDLEY.
